Dell XPS 720 (silver metal case w/ red plastic)
Your Current Specs: 
q6600 2.4ghz intel core 2 quad / 
4gb, i think it's ddr2) / 
Motherboard NVIDIA nForce 680i SLI
BFG nvidia GTX 280 1GB ) / 
1000W - it's a special size, don't think it'll fit in the new build.  / 
Case - Dell XPS 720
Budget: $450
Main Use: 5 being Highest: 
Light Gaming-2, 
Gaming-5, 
Emulation (PS2/Wii)-3, 
Video Editing-4, 
HD Streaming-3, 
3D/Model work-5, 
General Usage (Word, Web, 1080p playback)-2. (that's what the linux partition is for)
Monitor Resolution: 1080p/120hz (benQ... you know, the gaming one.) no, not upgrading for awhile.
List SPECIFIC games or applications that you MUST be able to run well: 
3ds max,  STALKER: COP, Borderlands 2, BF3,
Is 30FPS acceptable? i really want at least 45fps. and i know i'm wasting my 120hz if it's under 60.
Will you use CUDA accelerated software? no idea.
Looking to reuse any parts?: my HDD - 1TB sata II, SSD - 120gb sata III, perhaps my BFG Nvidia GTX 280, optical drives. 
When will you build?: within the week, tho if you've got something else that's coming in 6 weeks, i'll listen... a price drop or a performance increase
Will you be overclocking?: about 500 mhz, not too much. doesn't turbo boost do the job adequately?
---okay. 
here's an accurate look at the specs:
   i want a smaller, lighter case, this one is 70+ lbs. i want a quiet computer, if that's feasible. i want a new mobo and a new CPU. i would like firewire and an optical toslink audio out. 
and you know how some cases put the HDD bays perpendicular to the case, so you can't add a pata-to-sata adapter? i hate that.

---someone suggest a micro ATX? i'm only ever gonna use 1 video card, i'll probably get a heat sink, if it would mean a quieter or longer lasting computer.
   i got the z77 for futureproofing. an i5k or i7k will be a major upgrade still, when the prices have dropped or when i have some more money?
   do i need a 550? i can't see myself spending more than $300 on a video card, unless you think i'll need it for 3ds max, building PC games...
   also.... what about AMD CPU's? no love?	
   yes, and something that i would REALLY like... is to make this a hackintosh. really i would. i need to see what kind of parts restrictions that will give me...
---anandtech comparisons of the q6600 CPU i have and the i3-3225 aren't enough to justify the $130, i think i'll bite the bullet now and get an i5-3570k, those numbers are all about doubled, for an extra $90. it's still in my budget, mostly.
